Update on US residential solar market

Update on US residential solar market

The solar industry has been slowly moving from government driven subsidized industry a decade ago, to one that is at grid parity in most markets, both in and outside the US. Solar has been able to achieve grid parity as Levelized Cost of Electricity is equal to or less than electricity delivered from the grid. California, Arizona and Hawaii were among the first states where solar energy achieved grid parity as sunshine is abundant/high number of sunny days and grid electricity prices are high. As a result, California has emerged as the largest solar market in US (based on megawatt installed), as shown in Exhibit 1.

In the US, government subsidies and credits for solar installations are largely being phased out; but governments continue to play an important role in setting mandates to drive solar adoption as it is at grid parity and solar is green/an environmentally friendly energy source. One upcoming mandate that was set in 2018 that could serve as major growth driver for the industry is the California state mandate requiring every new residential home (three stories and under) built in 2020 to have a rooftop solar system. Goldman Sachs estimates rooftop solar was installed in 15,000 homes out of a total of 130,000 residential homes built in 2018. Assuming similar number of homes built in 2020, the new mandate would subject an additional 115,000 homes to be installed with rooftop solar, indicating a material step-up to current run rate.

Meanwhile, 10-year interest rates have declined materially over the last 12 months (Exhibit 2), bringing solar installers cost of capital lower and thereby making monthly cost of having rooftop cheaper.

With new mandates going in to effect and interest rates lower than any time in the last 18 months, strong growth drivers are in place for the US residential solar market in 2020. We are actively looking at investment opportunities in companies that have unique leadership position and are set to benefit from the growth in the US residential solar industry.
